Application filed February 12, 1913.

Z '0 all whom it may concern Be it known that I, RICHARD 1. SMITH, acitizen of the United States, residing at Grofton, in the county of Knoxand State of Nebraska, have invented a new and useful FourHo-rse Evener,of which the following is a specification.

The device forming the subject matter of this application is an eveneror draft equal- Serial No. 748,045.

segments, the shorter segment projecting to the right of the clevis andthe longer segment projecting to the left of the clevis. Braces 26diverge from the plow beam B and are secured to the main beam 1.

A. primary lever 2 is located in front of the main beam 1. Attached tothe right hand end. of the primary lever 2 is a clevis 10, the rear endof which is pivoted to a clevis 11, the clevis 11 being attached to theizer, adapted, primarily, although not neces 1 sarlly, to equalize thedraft among four right hand end of the main beam 1. A bell horses whenthe same are attached to a plow. crank lever 9 1s fulcrumed on the right.One object of the present invention is to effect an equitabledistribution of the load among. the several draft animals.

Another object of the invention is to pro vide novel means whereby,through a movement of certain constituent. portions of the equalizer,the load will be fairly distributed among the several draft animals whenthe thickness of the furrow-slice is changed.

It is within the scope of the invention to improve generally and toenhance the utility of, devices of that type to which the presentinvention appertains.

With the above and other objects in view which will appear as thedescription proceeds, the invention resides in the combination andarrangement of parts and in the details of construction hereinafterdescribed and claimed, it being understood that changes in the preciseembodiment of the invention herein disclosed can be made within thescope of what is claimed without departing from the spirit of theinvention.

In the accompanying drawings :Figure 1 is a top plan; Fig. 2 is a sideelevation; Fig. 3 is a fragmental cross section on the line 3-3 of Fig.1; Fig. i is a fragmental cross section on the line 4-4t of Fig. 1.

In the accompanying drawings there is shown a plow P, the beam thereofbeing denoted by the reference character B. The beam B supports asegment S to which is pivoted a lever L provided with latch mechanism Mof any desired sort, cooperating with the segment S to hold the lever Lin adjusted position. Mounted upon the forward end of the plow beam B isa clevis 25 attached to a main beam 1. Presupposing that the reader isfacing in the direction in which the plow P is moving, the clevis 25 issecured to the main beam 1 at a point nearer to the right hand end ofthe beam than to the left hand end of the beam, the clevis 25, dividingthe beam into unequal and 11.

hand end of the beam 1, the bell crank lever cmnprising a forwardlyextending arm which is pivotally connected with the securing elementwhich unites the clevises 10 In this manner, the bell crank lever 9 isconnected with the primary lever 2 so as to move the samelongitudinally, and in a direction substantially parallel to the mainbeam 1. A connection C unites the extremity of this last specifiedsegment of the bell crank lever 9 with the latch lever I1.

Mounted on the primary lever 2 at a point intermediate its ends is aclevis18, connected with the central point of a triple tree 6. Thetriple tree 6 carries adjacent its ends, clevises 12 supporting doubletrees 7 and 8. The outer ends of the double trees 7 and 8 are shorterthan the inner ends thereof. A link 22 is secured to the inner end ofthe double tree 7 and a link 23 is secured to the inner end of thedouble tree 8 and these links converge and pivotally unite with aswingle tree 5. A link 21 affords union between the outer end of thedouble tree 7 and the intermediate portion of a swingle tree 5 A link 24affords a pivotal union between the outer end of the double tree 8 andthe intermediate portion of a swingle tree 5 A clevis 17 is attached tothe left hand end of the main beam 1, the clevis 17 including an upperarm 17 and a lower arm 17*. A pivot element 100 passes through the arms17 and 17 of the clevis 17 and alfords a pivotal mounting for anauxiliary tree 8, the tree 3 being pivotally supported at a point midwaybetween its ends. An eye bolt 16 is mounted upon the right hand end ofthe auxiliary tree 3 and is connected through the medium of a link 15with an eye bolt 1 1 mounted on the left hand end of the primary lever2. Supported upon the main beam 1 and alined vertically with theforwardly extended lower arm 17 of the clevis 17 is a link 18, therebeing a pivot element 101 connecting the arm 17 and the link 18. Theright hand end of a secondary lever 4 is pivoted upon the element 101. Athreepart connection shown in Fig. 4 and indicated by the referencecharacter 19, unites the left hand end of the auxiliary tree 3 pivotallywith the intermediate portion of the secondary lever 41, that part ofthe lever l lies to the left of the connection 19 than that part of thelever the right of the connection. Pivoted to the outer end of thesecondary lever 4 are links 20, the forward ends of the links 20 beingconnected to the central point of a swingle tree 5.

The efforts ofthe three draft animals attached to the swingle trees 5,5" and 5 are transmitted to the double trees 7 and 8, thence to thetriple tree 6 and from the triple tree 6 by way of the clevis 13 to theintermediate portion of the primary lever 2. From the primary lever 2the pull is transmitted to the right hand end of the bar 1 through theclevises l0 and 11. From the left hand end of the primary lever 2, thepull is transmitted through the link 15 to the right hand end of theauxiliary tree 3, this pull being offset by the pull of the single draftanimal attached to the draft tree 5, from which element the pull will betransmitted by the links 20, to the secondary lever 4 and by way of theclevis 19 to the auxiliary tree 3. In this manner, the pull will beequitably and evenly divided among the several draft animals.

When it is desired to regulate the width of the furrow-slice, the leverL may be moved upon the segment S actuating the connection I] to imparta movement to the bell crank lever 9, the latter producing relativeparallel movement between the main beam 1 and the primary lever 2 andattend- 4 which being longer which lies to 4 ant parts.

Having thus described the invention, what is claimed is 1. In a draftequalizer, a main beam; a primary lever pivotally connected at its outerend to one end of the main beam; a draft tree pivoted to theintermediate portion of the primary lever; a supplemental tree pivotedbetween its ends to the other end of a connection between the inner endof the supplemental tree and the inner end of the primary lever; asecondary lever pivotally connected at its inner end to said other endof the main beam; a connection between the intermediate portion of thesecondary lever and the outer end of the supplemental tree; and a drafttree pivoted to the outer end of the secondary lever.

2. In a draft equalizer, armain beam; a primary lever pivotallyconnected at its outer end to one end of the main beam; a draft treepivoted to the intermediate portion of the primary lever; a supplementaltree pivoted between its ends to the other end of the main beam; aconnection between the inner end of the supplemental tree and the innerend of the primary lever; a secondary lever pivotally connected at itsinner end to said other end of the mainebeam; a connection between theintermediate portion of the secondary lever and the outerend of thesupplemental tree; a to the outer end of the secondary lever; and alever fulcrumed on the main beam and pivoted to the primary leveradjacent the connection between the primary lever and the main beam.

3. In a draft equalizer a main beam; a supplemental tree pivotedintermediate its ends to one end of the main beam; a secondary leverpivoted to the main beam; a connection between the outer end of thesupplemental tree and the intermediate portion of the secondary lever; aprimary lever pivoted at its outer end to the other end of the mainbeam; a connection between the inner end of the primary lever and theinner end of the supplemental tree; and means carried by the main beamand operably connected to the primary lever for producing relativemovement between the primary lever and the main lever in a directionapproximately parallel to the. main beam.

In testimony that I claim the foregoing as my own, I have hereto affixedmy signature in the presence of two witnesses.
